The most famous waste products (hereinafter referred to as "organic PT")
As a low running cost treatment method that does not require the use of blowers, etc., instead of aerobic treatment (referred to as "B liquid"),
Anaerobic execution methods are attracting attention. This anaerobic (digestion)
The treatment produces less sludge and uses methane gas.
It has the advantage of being able to recover energy.

ている。Furthermore, this t1flj pneumatic treatment also involves an acid production reaction in which the organic matter in the organic waste liquid is converted into volatile organic acids such as acetic acid, propionic acid, and butyric acid by the action of anaerobic liquefaction bacteria (septic bacteria), and then kneading. A two-phase anaerobic (digestion) treatment method has been proposed that separates the gasification reaction (methane production reaction) into two phases, in which the organic acids produced by methanogens are converted into methane by methanogenic bacteria.

ることに成、功り、た。It is well known that this two-phase anaerobic treatment method has a much more effective treatment effect than the conventional weighing method, which involves fermentation in one tank. As a result of further research into the reaction and the methane-producing reaction involved in it, we were able to obtain the knowledge that the anaerobic treatment reaction could be accelerated by utilizing sulfuric acid-reducing bacteria. We have also succeeded in obtaining an anaerobic treatment method for organic wastewater with superior treatment efficiency.

COs+5Oi- As is clear from the above formula, propionic acid is decomposed to acetic acid. At this time, for each mole of propionic acid, 1 mole of vlc acid ion is required. The amount of intoxicating ions used for adding intoxicants is 0.3 to 3 times the organic carbon in the waste liquid.
By having a molar ratio of 1 or more, each organic acid can be effectively decomposed to acetic acid.

By adding the above-mentioned ions to the acid production reaction tank and mixing and stirring anaerobically in the same manner as in the conventional acid production reaction, it becomes possible to convert the organic matter to the form of acetic acid.
